EZShout

TP EZShout is an alternate Internet Radio directory service for the SMC EZ-Stream [1 ].

http://www.smc.com/images/products/400/SMCWAA_G.jpg

On advice of a friend, I recently found one of these devices for $35 USD (April 2007) [3 ] or [2 ]. Seems too cheap to pass up.

The EZ-Stream plays MP3 and WMA audio, either from Internet Radio [6 ], a UPnP media server, [5 ], or from RHAPSODY Digital Music Server (which I haven't used since it's Windows only.) The EZ-Stream seems to be an implementation of a design by BridgeCo [4 ].

My main interest was to get Internet Radio through my home audio system, and this device works well for that purpose. As a bonus, I found that it can also access my personal library of ripped CDs through use of a UPnP media server. I'm running GMediaServer [7 ] for that usage. Other formats (AAC, Ogg, etc.) are not supported by the EZ-Stream.

One downside of the EZ-Stream is that the Internet Radio directory is a subscription service after a 60-day trial. While the expense is not that great (one-time fee, $30 USD), this fee was not mentioned anywhere on the SMC product site, product packaging, retailers pages, etc. (Can you say Bait and Switch?) Also, I wanted to be able to control my Internet Radio directory, accessing stations not in the SMC list, and excluding others of which I would never listen. Shoutcast.com [8 ] is a rich source of Internet Radio stations listed by genre. Shoutcast directories by genre can be downloaded in XML format, and a .pls playlist of an internet radio station can be retrieved by a Shoutcast ID.

Through use of an old friend, sockspy, I was quickly able to see how the EZ-Stream updates its directory list: a simple HTTP request that retrieves an unencrypted XML file containing a list of station URLs and a directory structure.

Seems like a plan.

I ended up writing a Shoutcast to EZ-Stream directory converter, EZShout. One problem I ran into is that the EZ-Stream seems to only recognize a URL to the actual MP3 or WMA stream of an Internet Radio station. Shoutcast returns a playlist in .pls format [9 ] when queried, instead of an actual URL to a stream. It's also not recommended to pre-fetch possibly thousands of playlists from Shoutcast, so some sort of on-the-fly translation is needed.

My solution is a small CGI redirector, nph-sc-redir.cgi, that fetches a Shoutcast .pls playlist, parses out the stream URL(s), connects to the stream and uses my local webserver as a proxy. If anyone figures out how to make the EZ-Stream play a .pls (or .m3u) playlist file, feel free to share. This is a shell script that evolved from a simple one-liner during testing. Probably could have been a nice little Tcl script implementing a custom HTTP-to-ICY server.

Here's how to make all of this work (Linux/Unix only at this time):

  1. Configure your EZ-Stream, and get familiar with how it works, especially the settings menu.
  2. You'll need a webserver running on your local network. I use thttpd [10 ] running on my NSLU2 Slug (see Tcl on the Slug).
  3. Create a directory in your webserver root /setupapp/smc2/asp/rsdb, and enable CGI execution for this directory.
  4. Copy the three files below to that directory. Make sure that update.asp and nph-sc-redir.cgi are executable.
  5. Note that nph-sc-redir.cgi should be run as CGI Non-parsed headers. It will be streaming the ICY protocol [11 ] instead of replying with an HTTP status code.
  6. Configure your directory as you want in ezshout.conf, as no doubt your musical tastes are different from mine.
  7. Also note other settings in ezshout.conf and nph-sc-redir.cgi that you may need to adjust. I limit usage to clients from my local network, as thttpd doesn't limit CGI or URL by IP address.
  8. Install Tcl8.4 and the tdom extension. For Debian Linux, simply sudo apt-get install tcl8.4 tdom.
  9. Instead, you can run Tclkit [13 ] and tdom.kit [12 ]. Change the executable in update.asp to use tclkit instead of tclsh.
  10. Install wget [15 ] and netcat (nc) [14 ] if you don't already have those.
  11. Setup a second network configuration on your EZ-Stream to use your webserver as an HTTP proxy. Instead of proxying the directory update request to the default site, your local webserver will process the request.
  12. Enable the proxied configuration on your EZ-Stream, and disable automatic directory updates.
  13. Now, perform a manual update. Mine often fails the first time, but works on second tries. Make sure that the directory is updated, and reports EZSHOUT as the directory service.
  14. Switch your configuration back to your original working, non-proxied setting.
  15. Now enjoy your music your way!! Note that you can update with the SMC Internet Directory service anytime, just update without configuring the EZ-Stream to use the proxy configuration.
  16. Debug any changes to ezshout.conf by cd'ing to /var/www/setupapp/smc2/asp/rsdb and executing ./update.asp -debug 1. This parses your config, prints your directory, and also retrieves a list of Shoutcast genres.
  17. Run GMediaServer also if you want. I run it on the same box as my webserver. (Debian Linux users: sudo apt-get install gmediaserver, configure to point to your .MP3 files)

Now the files. These files are public domain, do what you want with them.

 # directory : This defines the directory when the EZ Stream requests an

 #
 # directory is a Tcl list of one or more elements.
 #
 # Each element is a sub-list of three elements:
 #   {type  name   data}
 #
 # type:  is one of:
 #    DIR       Specifies a directory structure, data is sub-directory list
 #    SC_GENRE  Specifes the data is a Shoutcast genre, which will be expanded
 #               to each station.  data is a single element genre, or a list of
 #               {genre minBitRate}.  minBitRate should be an integer in kb/s
 #    M3U_URL   Specifies the data is a URL that directly plays a stream
 # name:  The name of the directory or station
 # data: As specified by type
 #
 # Restrictions:
 # 1. The first element must be a DIR.  This name shows up on the
 #    EZ-Stream main menu.
 # 2. Any sub-directory that contains an M3U_URL element may not contain sibling
 #    DIR or SC_GENRE types.  See "Favorite and Unlisted" in sample. In other
 #    words, a DIR may contain other DIR and SC_GENRE -or- M3U, but not both.
 # 3. SC_GENRE data must specify a valid Shoutcast genre.  If bogus, bad things
 #    can happen.  Run with argument "-debug 1" to get a list of Shoutcast genre

 #
 # get the shoutcast playlist (.pls) file from shoutcast.com, find the
 # first open url, connect to that url and streams
 #
 # requires standard unix utilities, wget, and netcat (nc)
 #
 # expects one cgi parameter: id  (shoutcast id for station playlist)
 # note that this script should be executed as "Non-parsed headers"
 # some webservers use the convention of prefixing the cgi
 # name with 'nph-' to run as "Non-parsed headers"
 #
 # for testing: use xmms, mpg123, etc.
